In Alpha I fly near enough the Unknow jump hole to get the wrecks showing on the map. Then I get to the Beta jump hole, there enable solar listing in the lower left hud. Then double click the first ship wreck shown and Target switch until normaly the 5'th wreck which should then show the Cerberus weapon. Then fly to it, loot and target switch again until the next wreck shows weapons and loot then repeat for the following 2 wrecks.
